Operating Systems Lab

This repository contains programs and assignments for Operating Systems Lab, implemented in C, C++, and Shell Scripting.

Folder Structure

• -Processes → Process creation, termination, zombie/orphan processes
• -Threads → Thread creation, joining, passing parameters, deadlock simulation
• -Scheduling → CPU scheduling algorithms (FCFS, SJF, Priority, Round Robin)
• -Synchronization → Producer-Consumer, Reader-Writer, Dining Philosophers
• -FileManagement → File operations using system calls (create, delete, copy, move)
• -ShellScripting → Basic shell scripts for system info, file handling, and automation

Compilation & Execution

C / C++ Programs

g++ filename.cpp -o output -pthread
./output




## Example Subfolder README (`03-Scheduling/README.md`)

# CPU Scheduling Algorithms

This folder contains implementations of CPU scheduling algorithms:

1. First Come First Serve (FCFS)
2. Shortest Job First (SJF)
3. Priority Scheduling
4. Round Robin (RR)

## Example Run (FCFS)

### Input


Processes: P1, P2, P3
Burst Times: 5, 8, 12
Arrival Times: 0, 1, 2



### Output


Gantt Chart: P1 | P2 | P3
Average Waiting Time = 4.3
Average Turnaround Time = 9.7
